Tappan Zee Constructors, LLC (TZC) has suspended construction operations at the project site today, Jan. 4, and Friday, Jan. 5, due to snow, high winds and freezing temperatures. TZC will continue to monitor conditions and respond to any weather-related issues. TZC will also maintain a marine patrol for safety and security, as well as a small crew for snow removal.

TZC’s inclement weather preparation protocols include inspecting and adjusting all mooring lines, inspecting crane barges and securing all equipment, having tug boats on the water to provide rapid response, moving the majority of cranes to shallow water moorings and taking all smaller crew boats out of the water. Additionally, TZC uses video and GPS to monitor the entire fleet of project vessels from its security operations center.


Operations will resume after a careful review of the project site, helping ensure the continued safety of the public and the project team.

Next week’s scheduled work includes:

  • Pier substructure work
  • Steel girder installation
  • Internal tower work
  • Electrical equipment installation and testing
  • Excavation and drainage work in Westchester County
  • Construction of Thruway maintenance and State Police facilities in Tarrytown

 Boater Safety

Expect periodic closures of the main navigation channel due to on-going construction and extensive demolition activities. Cranes, barges and other equipment will occupy parts of the channel during this time. Boaters are strongly encouraged to avoid the project site during the closures and to avoid the Regulated Navigation Areas, located east and west of the main channel.

Times and dates of the closures are subject to change and will appear in the U.S. Coast Guard’s weekly Notice to Mariners; on the project’s Twitter feed (@NewNYBridge); and broadcast on Marine Radio Channel 22A. Tappan Zee Constructors can be contacted via Marine Radio Channel 16 for assistance.

Rockland and Westchester marine units continue to patrol the project site.
